Koozebanian Phoob

The Koozebanian Phoob is a blue alien creature from the planet Koozebane who is interviewed by Kermit in episode 205 of The Muppet Show. The Phoob is a very unfortunate creature, because it is known as the most delicious creature on Koozebane. Luckily, the Phoob has hit upon a survival strategy -- it evolves very quickly into whatever is nearby. The sketch ends with the Phoob "evolving" into a clone of Kermit, causing the two Kermits to fight over which is the real one.
